WKK2 - Re-programming Tire Pressure Monitoring (TPM) Control Unit (Workshop
campaign)
Important:
CRITICAL WARNING -This campaign includes steps where control unit(s) in the vehicle will be
programmed with the PIWIS Tester. The vehicle voltage must be maintained between 13.5 volts and 14.5
volts during this programming. Failure to maintain this voltage could result in damaged control unit(s).
Damage caused by inadequate voltage during programming is not a warrantable defect. The technician
must verify the actual vehicle voltage in the PIWIS Tester before starting the campaign and also document
the actual voltage on the repair order
Model Year:
As of 2017 up to 2020
Model line:
Cayenne (9YA/9YB)
Subject:
Tire Pressure Monitoring (TPM) control unit
Information:
The wheel sensors of the Tire Pressure Monitoring (TPM) system transmit their remaining battery life to
the TPM control unit at regular intervals. The battery life is approx. 10 years.
Due to a software error in the TPM control unit, the relevant wheel sensor can fail on the
affected vehicles if a remaining battery life of less than 6 months is transmitted.
If this happens, the tire pressure from the affected wheel sensor will no longer be transmitted to the TPM
control unit, but no warning message to this effect is displayed in the instrument cluster.
Only when the battery in the wheel sensor is fully discharged is the failure detected and the corresponding
warning message is displayed in the instrument cluster.
Remedial
Action:
Re-program the tire Pressure Monitoring (TPM) control unit using the PIWIS Tester with test software
version 39.100.020 (or higher) installed.
Information
If campaign AKB8 or AKA0 is also open for the respective vehicle, this campaign must be carried
out together with campaign AKB8/AKA0. To do this, program the Tire Pressure Monitoring (TPM) control
unit by entering the programming code before carrying out the concluding work for AKB8/AKA0.
For instructions, see  Technical Information 'Re-programming Tyre Pressure Monitoring (TPM) control
unit'.
In this case, invoice Scope 1 during warranty processing  Technical Information 'Warranty processing'.
If campaign AKB8 and AKA0 was already carried out during a previous workshop visit or if the
vehicle is not affected by AKB8/AKA0, this campaign must be carried out as described here.
In this case, invoice Scope 2 during warranty processing  Technical Information 'Warranty processing'.

Required tools
Tools:
•
•
9900 - PIWIS Tester 3 with PIWIS Tester software version 39.100.020 (or higher) installed
Battery charger with a current rating of at least 90 A and a current and voltage-controlled
charge map for lithium starter batteries, e.g. Battery Charger, 90 A
Preparatory work
NOTICE
Fault entry in the fault memory and control unit programming aborted due to low-voltage.
•
Increased current draw during diagnosis or control unit programming can cause a drop in voltage, which
can result in one or more fault entries and the abnormal termination of the programming process.

Before starting control unit programming, connect a suitable battery charger with a current rating of at
least 90 A to the vehicle.
NOTICE
Control unit programming will be aborted if the WLAN connection is unstable.
•
An unstable WiFi connection can interrupt communication between the PIWIS Tester and the vehicle
communication module (VCI). As a result, control unit programming may be aborted.

During control unit programming, always connect the PIWIS Tester to the vehicle communication module
(VCI) via the USB cable.
NOTICE
Control unit programming will be aborted if the driver's key is not recognized
•
If the driver's key is not recognized in the vehicle, programming cannot be started or will be interrupted.

Place the driver's key with the back facing down into the front left storage compartment in the center
console to guarantee a continuous radio link between the vehicle and the driver's key.

Drive at a speed of more than 25 km/h (15 mph) - ideally without stopping - until the tire pressure
values are displayed (learning time: less than 2 minutes).
The system learns the wheel electronics only while driving. Intermediate stops and deviations from the
described teaching procedure can result in a much longer learning time.
Teaching can be performed during the test drive or later while the customer is driving. Please inform your
customer about this if necessary.
